We have been having a lot of fun with the fridge magnets activity that is found in SMART Notebook. Search for fridge in the Gallery and look in the Interactive and Multimedia folder.
We put the screen in dual page mode. One student creates a word by dragging the letters onto the playing surface and then whoever else is playing, tries to write as many words as they can in two minutes. They can even check the spelling by recognizing the words as text and looking to see if there is a wiggly red line under the letters. If there is, they can correct it by right clicking on the word.
This makes a fun learning activity center in our classroom!
